New Scientist is a weekly English-language international science magazine, founded in 1956. Since 1996 it has also run a website.

Sold in retail outlets and on subscription, the magazine covers current developments, news, reviews and commentary on science and technology. It also publishes speculative articles, ranging from the technical to the philosophical. A readers’ letters section discusses recent articles, and discussions also take place on the website.

Readers contribute observations on examples of pseudoscience to Feedback, and offer questions and answers on scientific and technical topics to Last Word; extracts from the latter have been compiled into several books.

New Scientist, based in London, publishes editions in the UK, the United States, and Australia.
